Description
The authors developed a high-resolution quantitative history of temperature variability over the past 800 years, based on analyses of diatoms found in a sediment core retrieved from a treeline lake - Lake Tsuolbmajavri (68°41'N, 22°05'E) - in Finnish Lapland. It revealed that what they call the "termination phase of the MWP" - which they indicate as having occurred between AD 1200 and 1300 - was 0.15°C warmer than the peak warmth of the Current Warm Period, which in their history occurred at the conclusion of the 20th century.
